Title: Circuit for restoring analog video signal to digital video signal
Inventor: WATANABE YASUSHI
IPC: G09G5/00
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a circuit for restoring an analog video signal to a digital video signal capable of A/D converting using a stable clock signal. SOLUTION: A crystal oscillator 5 outputs the clock signal S4 having a frequency of four times of the dot clock of the analog video signal S1, and a clock generation part 6 generates eight clock signals S7 with the same frequency as and a phase different from the dot clock of the analog video signal S1 by shifting at the rise and the fall of the clock signal S4. A phase comparator 7 compares the phase of a horizontal synchronizing signal S3 with the phases of eight clock signals S7 to output these results, and a clock selector 3 outputs the optimum phase clock signals S6, S8. An A/D conversion part 1 restores a stable leveled analog signal S1 to the digital signal S5 by this A/D sampling clock S6.
